If you think about it in price per meal, it may not seem as expensive. Nekton-Lori recommends 10 g of food per day per lorikeet. A jar of 750 g is therefore 75 meals. For one lorikeet, that's less than a dollar per day!
Harrison's High Potency Fine 455 g is $27. Our African Grey gets through that bag in about three weeks. That's about $1.28 a day!
We can source it but we do not stock it by default. This is because Harrison's recommends that their bags are used up within six weeks of opening. Unless you have many birds, it'd be hard to get through such a bag. Our African Grey goes through a 455 g bag of High Potency Coarse in about three weeks. So a 2.27 kg bag may be more appropriate for two large birds. For small birds, we always recommend 455 g bags.
